the diameter of the test balls ranged from 1.27 to 3.81 cm. pre-grinding of the clinker in the test ball mill for a few minutes before preparing the test samples. if the crushed clinker is used as such, as is the general practice, the initial grinding rates obtained are not representative of the particles produced in the ball mill under the test conditions.
process of cement grinding. main equipment in cement grinding line--cement mill. cement ball mill is the key equipment in the cement grinding process. ftm cement ball mill adopts high chromium alloy steel or double medium quenched steel liner, which has the characteristics of high quenching hardness and high toughness. the wear in production is small.
most of the cement ball mills are used in the circulating grinding system, which is characterized by high grinding efficiency, large mill output, and low power consumption. especially when grinding slag cement, the performance is more outstanding, compared with the general mill.
in the cement manufacturing process, each producing 1 tons of cement grinding material at least 3 tons including fuel, clinker, gypsum, mixture and all kinds of seven trust materials , according to statistics, dry process cement production line grinding operation requires more than the consumption of power plant power accounts for about 60%, the seven trust material grinding accounted for more than 30%, coal mill about 3%, accounting for about 40% of cement grinding.
cement grinding using grate discharge principles developed in the ore milling industry applied to the cement industry. this experience plus the years of manufacturing know how unquestionably qualify grate discharge grinding for the cement industry. seven trust cement grinding. this phase of grinding may be either the wet or dry process, the end product going to a kiln.
after the material is broken into the ball mill grinding, grinding operation is the key equipment indispensable. cement industry equipment can grinding various ores and other materials are widely used in a variety of industries such as mineral processing, building materials, chemical widely used, especially for grinding sand, lime, gypsum, slag and other materials common. cement industry equipment machine is widely used in industrial production, particularly in the mineral processing
